Answer 1

a) Volume: 770 cm^3
Work: V = l*w*h = 11*7*19 = 770
Surface Area: 514 cm^2
Work: 110+110+77+77+70+70 = 514

Surface area = (2)(10)(7) + (2)(11)(7) + (2)(11)(10) = 1774 square centimeters

b) Surface area (How much wax can cover the cube)

c) Volume (How much juice will be inside the cube)
